초록

Chlorine을 다량으로 함유하고 있는 산업 폐부산물의 시멘트 키른을 이용한 소각 가능성을 검토하고자 OPC에 KCl을 함량별로 첨가하여 수화발열, 응결시간, 유동성, 길이변화 및 몰탈 압축강도를 측정하였다. 실험결과 KCl를 첨가함에 따라 수화가 촉진되어 유도기가 짧아짐으로써 응결시간이 짧아지고 유동성이 하락하며 초기수축이 커지고 3일 이전의 초기 압축강도는 상승하나 7일 이후의 후기 압축강도는 크게 하락하였다.

In order to examine the possibility of incineration of inderstrial by-product and wastes which contains a large percentage of chlorine by the cement kiln, measured heat of hydration, setting time, flow, change of length, compressive strength of OPC by the amount of KCl. The result was that a shorter setting time, a lower flow, a increasing the degree of initial shrinkage, a increasing of compressive strength before 3 days and decrease after 7 days by the induction period is shorter as promote the hydration with KCl.
